OffsetWindowOrg

Syntax

DWORD OffsetWindowOrg(hDC,X,Y)

This function modifies the viewport origin relative to the current values. The formulas are written as follows:

xNewWO = xOldWO + X
yNewWO = yOldWO + Y

The new origin is the sum of the current origin and the X and Y values.

Parameter

X	int Specifies the number of logical units to add to the current origin's x-coordinate.
Y	int Specifies the number of logical units to add to the current origin's y-coordinate.
